Bacillus and Virgibacillus strains isolated from three Mexican coasts antagonize Staphylococcus aureus and Vibrio parahaemolyticus.

摘要: This study identified marine microorganisms from Mexican coasts that had antimicrobial activity against Staphylococcus aureus and Vibrio parahaemolyticus, which are known worldwide to be food-poisoning agents. Representative specimens of algae, saline sediment, crustaceans mollusks were collected. Of the 42 tested strains, 15 inhibited these pathogens. Bacillus Virgibacillus strains by 16S rRNA gene sequencing. The with highest inhibitory S. PCRS1-07 (B. aerius), BLCG-05 GUO-01 pumilus). GUHC-04, BLCG-05, GUHC-03 altitudinis) BLBSe-05 oryzicola) showed higher V. parahaemolyticus. Biofilm production all was moderate, but B. altitudinis produced a stronger biofilm. is first isolate aerius, oryzicola, safensis, boroniphilus, senegalensis ecosystems in Mexico as well report their effects both Bioactivity spent media antagonistic cultured biofilm also demonstrated high activity. active compounds antagonists currently being studied tested. Marine have bacterial diversity associated invertebrates seaweed; however, this has not been well-studied on coasts.
